Corey, D, and Jessie sit down with Robin Linus of ZeroSync — the team spearheading the development of proof systems for Bitcoin for scalability, interoperability, and privacy. Robin discusses everything from the recently published BitVM white paper, challenges and tradeoffs of validation proofs on Bitcoin, ZK coins, and his birthday cake from Gisele Bündchen.

35:42|Is ETH a shitcoin to you? Money needs to be designed on mathematics, not trust

37:15|Data availability problems and solutions

40:50|Tradeoffs of any chain as it scales. Bitcoin is and always will be proof of work
